Cacklin" Hens :
you can house them with your chickens, but I personally believe guineas should be free range because in the wild they aren't penned up.Guineas are wild birds, therefore they should be free ranged i believe. Their natural diet includes bugs, grass, and other things they get outside. They cant get those things cooped up. you cam feed them chicken feed during the summer when they can get bugs and stuff outside. Thats if IF they are free range. If they are cooped up and also during the winter they should be on high protein gamebird feed (like 28%) Hope this helps
In the summer, free ranging Guineas should not have a problem with their diet. They are pretty hardy and they really do take care of themselves if allowed to roam your property. They should have a quiet, secure shelter (draft free) for the night hours that is predator proof if possible. They do not do well if they get wet and then experience a cold night.
During the winter they REALLY need the high protein food. The chickens will eat it of course, but the Guineas will eat their food too. They do not lay during the winter months and this can be a blessing. Guinea hens like to roost HIGH, be sure to have a few rafters available to them if you can.
ALWAYS keep fresh, clean and cool water available to your Guineas. They do not tolerate dirty water and will NOT drink it. I know, I have seen it first hand. They LOVE bowls of fresh water or water from a hose on the ground during the warm months.
When it rains, let them out. It will not harm them unless it gets cold during the night and they are still wet. Guineas LOVE to run, they do not do well cooped up.
